Place the laser on a flat surface or tripod 100 ft (30 m) away
from a wall. Position so that X' (noted on top of laser) is
facing the wall.
Turn on the laser.
Mark the location of the center of the beam. If it's too bright
to see the beam, use the detector.
Rotate the laser 180 degrees so that X faces the wall.
Mark the location of the center of the beam near the first
mark so that both marks are in line, one above the other.
At 100 ft., the marks should be no more than 3/16" apart. (At
30 m, no more than 5 mm apart.) This is within the stated
accuracy of ± 3/32" at 100 ft. (± 0.0075%).
If the marks are close enough, X axis is within calibration.
The second axis Y must then be checked (see later
section).
If the marks are not close enough, the X axis needs to be
calibrated.
